.- spinning nozzle or one group of spinning nozzles y two bobbins ,are-provided which are mounted on a tiltable carrier extending: longitudinally of the machine. The bobbins are arranged on spindles which are parallel toY the bobbin carrier Yand which engage in gear wheels of the driving shaft. 'They are adapted to be alternatelybrought into operative and inoperative position. Reciprocating thread guides are provided to windthe threads in crosswindings on the spools. Each of the spindles may be pivotallyk mounted and may be swung out to replace the uilyzwound bobbin by an empty one. Another Vconstruction provides a dead' space for the exchanging of the fully wound bobbins. These machines, however, require large longitudinal space, are rather complicated, and Ydifficult in operation.v Moreover, the threads must bev torn ",oii` by hand and the broken ends laid on the empty bobbins.

Another machine has been proposed wherein each two bobbins together witha` spinning'nozzie are combined: to form a spinning element Vand only one'bobbin'is being driven at any time. LEach pair of bobbins is in this case tiltable about a shaft disposed transversely of the machine. When a bobbin is fully wound, it is swung out ofv the working position, the empty bobbin is simultaneously swung into the working position,

., the thread broken oil by hand and the other end .attached tothe empty bobbin. The fullxbobbins are then replaced by empty ones, whilst the spin- :ning process is in progress, whereby the process is renderedcontinuous.

ZDueto the duplicated arrangement vof the bobbins on shafts disposed transversely of the machine, the overall length of the machine is undesirably large and` thereforer uneconomical.

y The object ofthe present invention ,is a bobbin spinning machine for the manufacture lof artic-ial silk which vis such that the above mentioned disadvantages are avoided. This ymachine is of the kind in which a .plurality of bobbins are providedffor .each spinning nozzle, of Which one only is always in the working position While another one is lbeingreplaced by van empty bcfbbin. yThecharacteristic feature of the kinvention consists in arranging the lbobbins kin opposition in two or vmorerowson a carrier member mountedin a tiltable manner to extend longitudinally of the machine. As soon as the bobbins in the operative position have been filled, the bobbinsare simultaneously ,swung around by rotation jofthe carrier member. Thread transferrersare mountedon the carrier memberand, duringthe movement of thelatter, take hold of the individual threads, lift them 01T the full -bobbinsAandv-delect them on to the CII empty .bobbins 4 Thethread trans-errers are provided, forthis'purposavwith arest which receives the'threadwhenthecarrier member is tilted, and with an inclinedthread deector, valong which the thread slides on to the displaced empty bobbin.

The transferred threadcomes against the periphery of a thread cutting disc on the bobbin `holder and is therecutoi. e v,

lt .is preferabletoprovide the machine with a device, which ensures that only the bobbins disposed in the operative position aredriven whereas the other-bobbins remain stationary. .A separate vdriving ygear is .therefore provided for Veach `row .of bobbins which can be thrown into or out of rengagement' .as desired.

This is .preferably efrected by means of an ,alternate-coupling.device i so constructed that, upon the .throwingof the onerow of bobbins into gear, Vthe otherbobbins are simultaneously Ydisengaged andcome to rest. This alternate-coupling jdevicemay also be operated. automatically by', the` 'swinging of the carrier member..A c f If groups of more than two bobbinsbemounted modified so'that, Aat any onetime, only one'row on the carriermember, thearrangement 'may-be f of bobbins isvstatio'nary while the 'bobbins o the other rows are being rotated, so that,for example, of thesev latter rows one may be' being wound "and another,for instance, kmay beV being washed with liquids, while rotating in Aa trough, adjustat replaced by empty bobbins.

ble as regards height, provided on the machine for this purpose.

It is of advantage in the tending of such a machine to have it constructed non-symmetrically. Hereby is avoided the disadvantage that the one or other row of bobbins, whether it be that disposed in the operative position or that disposed in the at rest position, is disposed in the interior of the machine and is in consequence difficult of access. It has been found advantageous to provide the spinning bath and the thread guides, together with the row of bobbins disposed in the operative position, on the one side of the machine, whilst the row of bobbins in the at rest position is arranged at the rear side of the machine. It is much easier and simpler to replace the fully wound bobbins from this side of the mad chine, as they are stationary and easily accessible. The separate drive for each row of bobbins may be effected for example, by means of two shafts mounted in the tiltable carrier member and driving, through worm gearing, the stub shafts upon which the bobbins are mounted. A train of gearing is provided for each of the individual driving shafts to allow of the attainment of the automatic drive, these' trains being alternately connected with the driving shaft through idle gear wheels and a rotary wedge clutch.

The machine according to the present invention exhibits all the advantages of the hitherto imown types of machines. By reason of the novel arrangement of the bobbins the machine only has a small' overall length in the longitudinal direction, which is the direction of primary importance as regards space requirements. Furthermore the operation of the machine is continuous due to the employment of a plurality of bobbins and the arrangement thereof on a tiltable carier member.

`The employment of thread transferrers and thread cutting discs allows of a mechanical and automatic transference of the thread during the exchange of the bobbins. In addition, the transference is effected at all bobbins lsimultanuously whereby uniformity of the thickness of the wind-- ing is ensured. It is of advantage furthermore that the bobbinsto be replaced are not disposed on the same side of the Vmachine as thebobbins being wound, whereby negligence in the tending of the machine .does not give rise to the danger, as hitherto, of an interruption in the spinningI process.

The separate drive of each row of bobbins has the advantage that the bobbin holders which are thrown out of action can be stopped so that the fully wound bobbins may be easily removed and The automatic regulation of the drive by means of an alternate-coupling device, which is actuated by the displacement of the carrier member, ensures operation without loss of time and material. Y

In order more particularly to describe the na-I ture of this invention, reference will be made to the accompanying drawings, Whereinz- Fig. 1 shows a one-sided, unsymmetrical machine with the thread-transferrers and a sep-1 arate drive for each row of bobbins, in sectionalsideA elevation;

The machine frame 1 has rotatably mounted thereon, in bearings 19 arranged one on each side in the longitudinal direction, a tubular carrier member 7, in the interior of which are mounted the bobbin driving shafts 6 and 6. The bobbins 10, 10 are mounted on the carrier member in two opposed overhanging rows. The bobbins are formed as sleeves which are pushed on bobbin holders comprising hollow cylindrical bodies 11, 12 and stub shafts 8, 9 secured thereto, respectively, these stub shafts 8, 9 being journalled in the wall of the carrier member 7 and projecting within the latter to receive worm wheels 13, 13', respectively, which mesh with worm Wheels 35, 35 on the driving shafts 6 and 6' respectively. On the inner end of the hollow cylindrical bodies 11 and 12 are mounted respective discs 15 and 15 each having a peripheral cutting edge formed with a number of notches shown respectively at 14 and 14'. Thread-transferrers 17 and 17 each bent a number of times, are provided for each bobbin, being formed to provide. a rest 16 or 16 on the'one side and to an inclined diverting member 13 and 18', running out to the bobbin In the `precipitating bath trough are arranged the usual spinning nozzles 2 from which the threads 3 are led to the bobbins 10 by way of the thread guides 5.

' Above the row of bobbins 10 is disposed the oscillating spindle 20 for the thread guides 5 this spindle receiving its motion from an eccentric or heart cam 22 through a lever 23. The driving shafts 6', 6 are provided at their ends withspur gear wheels 24, 25 respectively. wheels 24, 25 mesh with gear wheels 26, 27 mounted on shafts 28, 29 on the carrier member 7. On these shafts are loosely mounted gear wheels 3l), 31 which are continuously driven by the gear wheel 34 on the driving shaft. In order to drive the one or other Vof the driving shafts 6, 6 the gear wheel 3G or 31 is alternatively coupled by means of a rotary wedge coupling 32 or 33 with the shaft 28 or 29, respectively, so that the drive is transmitted through the gearing 26, 24 or 27, 25 respectively, to one' of the driving shafts 6', or 6. The engagement and disengagement of the couplings 32, 33 may be effected either by hand or automatically by means of the belt guiding member which is displaced along conical bodies so as to make the speed of rotation of the driving shafts 6', S agreewith the changing circumference of .the bobbins.

The method of operation ofthe machine will now be explained with reference to Figs. 1, 4, 5, and 6. During the Winding of the bobbins 10 the empty bobbins v10 are fixed in place. After the bobbins are fully wound, the carrier member is rotated around its longitudinal axis in the bearing 19, through 180 so that now the bobbins 10 are being wound, whilst the full bobbins l0 are shifted to the other side for changingrp'urposes.

During thisV rotation of the carrier member '7 the thread 3 first comes to bear on the rest 16 of the thread transferrer 17, then moves along the diverting member 18, which inclines towardsthe bobbin axis, until it is caught in the notches 14 in thecutting disc l5 on the. holder 12 supporting the bobbin 10', and broken there- These gear by, whereby the full bobbinlO is freed from the thread 3 whilstr the other end-,of the thread 3 is gripped by and wound upon thebobbinlO., whichv has vmeanwhile attained to its frontposition, the full bobbins 19 nowdisposedin the rear position being capable ofv Vbeing replaced by empty bobbins. In this manner the transferring of the thread from the full bobbin to the empty bobbin is effected automatically and without interruption of the spinning operation.

As the carrier member is being rotated the bobbin 10 is set in motion due to the fact that the gear wheel 30 is coupled with the shaft 28 by the engagement of the coupling 32, so that the shaft 6 and, consequently, thebobbins 10 are set in motion through the gear wheels 26, 24. After the rotation of the carrier member has been effected, the coupling 33 is disengaged to causer the gear wheel 31 again to run freely on the shaft 29, thus allowing the bobbin shaft 6 and, therefore, the bobbinsY l0 also, to come to rest. Whilst the bobbins 10 are being wound, the replacement of the full bobbins 10 by empty ones may now be effected.
